... Except you won't have minions on the board for any of those but Devilsaur Egg since they will die.

no it doesn't... end of turn effects trigger once. in this case, the cube dies, and its effect triggers after the end of turn step. two obsidian statues are summoned, but they aren't killed because the end of turn step is over. it's sort of like when y'shaarj summons ysera, but ysera's end of turn effect doesn't trigger. there's only one end of turn step and it happens once. the statues will die on the next turn, unless you can trade off your reckless experimenter or silence it or something. actually it's also possible that summoned (but not played) deathrattles will not be affected by reckless experimenter's aura. the card says that deathrattle minions you PLAY, not summon. of course, that's probably just referring to the mana discount. but it'd be sloppy wording, since there's no reason to specify that the mana cost only applies to minions you play. the only thing that can possibly cost you mana in the first place is playing cards. so that wouldn't be any different if it just said "your deathrattle minions cost 3 less." the only part that would be different is this issue of whether the second part (the minions dying) applies to minions you play, or your minions in general. it's entirely possible that blizzard just messed up the wording. they've done it before in the past so i can't say for sure. but if we're assuming this is exactly what they intended the card to read, then we can also assume the card's effect will only apply to deathrattle minions you play. just like hobgoblin or animated berserker. and unlike spiritsinger umbra.

If this card works exactly how it reads, then the Statues wouldn't die at all after the cube. Since they have to be played from hand to die at the end of turn. The double statue off cube isn't technically played from hand, and wouldn't be instantly killed next turn
